Why choose to be one superhero when you can be 10? Ben Tennyson is living every kid's fantasy when he stumbles upon a strange, watch-like gadget that possesses supernatural powers. The 'Omnitrix' gives Ben the ability to transform into any one of 10 different aliens, each with their own unique strengths and weaknesses. Changing guises as often as most kids change their socks, Ben assumes the freakish forms of Ghostfreak, Heatblast, Wildmutt, XLR8, and multi-limbed mutant Fourarms (as well as several other alien incarnations). Though Ben mainly uses the watch's powers for good, he cannot help but have a little mischievous fun with it along the way! Presented here is the twelfth volume of episodes taken from this clever and imaginative Cartoon Network show.
